The figure shows a rigid structure consisting of a circular hoop of radius R and mass m, and a square made of four thin bars, each of length R and mass m. The rigid structure rotates at a constant speed about a vertical axis, with a period of rotation of 3.5 s. If R = 1.0 m and m = 3.9 kg, calculate the angular momentum about that axis.

The figure shows a rigid assembly of a thin hoop (of mass m = 0.29 kg and radius R = 0.15 m) and a thin radial rod (of length L = 2R and also of mass m = 0.29 kg). The assembly is upright, but we nudge it so that it rotates around a horizontal axis in the plane of the rod and hoop, through the lower end of the rod. Assuming that the energy given to the assembly in the nudge is negligible, what is the assembly's angular speed about the rotation axis when it passes through the upside-down (inverted) orientation?
